Know your walk-away, and the zone where a deal is possible.
BATNA is your Best Alternative To a Negotiated Agreement — your benchmark for any offer. ZOPA is the Zone Of Possible Agreement — the overlap between what each side will accept. Together they tell you when to settle and when to walk.
When to use it
Before any negotiation, and whenever you're tempted to accept or reject an offer.
How to use it
1List your alternatives if there's no deal.
2Pick and improve the best one — that's your BATNA.
3Estimate the other side's BATNA too.
4Find the ZOPA — where your acceptable range overlaps theirs.
5Anchor near the edge of the ZOPA, not past it.
Watch out
Don't reveal your BATNA early; a weak BATNA is a reason to improve it, not to bluff.
Example
If a clinic's BATNA to a strike is a costly temp-staffing plan, and the union's BATNA is lost wages, the ZOPA is the settlement both sides prefer to those alternatives.
Takeaway
The side that knows its BATNA negotiates from clarity instead of fear.
